Gabriel's specially designed dampers for Specialized Applications feature a variety of piston bore sizes to provide customized damping for different designs and applications. Super finished, hardened, and chromed piston rod to provide for greater resistance to side loading. Also multi-lip piston rod seal provides backup seal protection and increased durability.
The Gabriel Steering Stabilizer supports steering assemblies on Kenworth, Oshkosh Motor, Peterbilt, and SAF Holland vehicles operating in environments where front-end components experience repeated shock inputs and side-loading. These stabilizers are designed with varying piston-bore dimensions to match different suspension architectures, allowing trucks to maintain smoother steering control when traveling over rough terrain, construction zones, or uneven municipal roads. The super-finished chromed rod resists wear from lateral load shifts, while a multi-lip rod seal provides additional sealing layers to guard against grime and moisture intrusion. This Gabriel 646177 offers an effective way to reduce abrupt steering movement and enhance straight-line tracking in heavy-duty applications.

Gabriel® delivers the performance and reliability that's trusted by truck and trailer O.E. manufacturers. Gabriel's industry history started in 1907 with the invention of the original automotive shock absorber. It was soon followed by the launching of the world's first hydraulic shock absorber, then by the first adjustable shock absorber as well as the first air adjustable shock absorber. Up to this day, Gabriel is still the same pioneering and independent American company that builds the high-performance shocks and struts that are designed to fit over 96% of North American vehicles. Gabriel remains one of the country's most trusted O.E.M. and aftermarket suppliers for light- medium- and heavy-duty trucks and vehicles.
